MyData service integrates and manages user's personal data such as finance, credit, etc, and is expected to provide useful information to the user as personal data in various fields are gradually integrated. Discovering factors that affect the intention to use of MyData service is a very important topic for understanding that service. To this end, in this study, the attributes of the MyData service were derived, and the derived service attributes were grouped together by using factor analysis. As a result, we found four factors such as "convenience", "usefulness", "security", and "control". After that, we established our research model to analyze the causal relationship between these four factors and the intention to use of MyData service. According to the analysis results, among the factors of the MyData service attribute, "convenience", "usefulness", and "control" had a significant effect, and "security" did not have a significant effect. In particular, it was confirmed that "control" had the greatest influence on the intention to use. This study suggests that MyData service provider need to make users recognize they are controlling their data and develop services that provide various benefits to users.

Smart TV is expected to take the center stage of the recent "smartization" trend in IT and consumer electronics as it performs a hub for various smart IT devices, such as smart phone, smart pad, PC, etc. It is distinct from traditional TVs or even IPTVs in the sense that it provides immersive and interactive experiences via apps downloaded through TV app store. Smart TV could serve as a new intermediary device between other smart devices and the Internet. While it started experiencing a rapid growth, little research has been conducted to understand this emerging technology in terms of its user acceptance and adoption by users. The current research attempts to fill the gap in the field by examining factors and processes for this new technology to be adopted by users. This paper draws on theories of IT acceptance and use, such as the "Unified Theory of Acceptance and Use of Technology", to investigate factors affecting "intention to use" of smart TV. The proposed research model is analyzed using the structural equation modeling approach. Findings show that such factors as innovativeness, switching cost, switching benefit, service interface, and user interface affect users' intention to use smart TV, through effort expectation, performance expectation, and social influence. Theoretical and managerial implications are discussed.

A meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. This study will find meaningful independent variables for criterion variables that affect influencing on purchase intention in social network service, on the basis of the results of a meta-analysis. We reviewed a total of 29 studies related on purchase intention in social network service published in Korean journals between 2000 and 2015, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study. Thus, we present the theoretical and practical implications of these results and discuss the differences between these results through a comparative analysis with previous studies.

In order to solve the current problems and inefficiencies within the Port Authorities (PA) in Korea, this study introduces the concept of the integration of PA and analyses the awareness of intention of integration. This study is based on analysing the surveys conducted by the members of PA. This research shows that there were different perceptions on the autonomy, business strategy intension, information sharing efficiency, competition, environment and technique change, capital finance, easy finance risk, curtailment of expenditure, personnel management efficiency in PA. Results of the study indicate that YGPA has more clear understanding on the awareness of integration of PA than other PAs. The results of this research will serve as a basic literature for further studies on the integration of PA in Korea. Moreover, the problems that have been identified and analysed in this study will contribute to establishing the strategy for further development of PA in Korea.

As virtual assistants rapidly diffused into the market, the voice shopping market is expected to expand. The purpose of this study is to identify the factors that determine the consumers' intention to adopt voice shopping by using the unified theory of acceptance and use of technology(UTAUT). In this study, we set variables that influence the intention to adoption of voice shopping with performance expectation and effort expectations as the variables of UTAUT and playfulness expectations as an extended variable. In addition, we also include four voice secretary attributes such as response accuracy, compatibility, social presence, and safety in our research model to investigate the source of motivation of voice shopping adoption. The result of this analysis shows that variables such as performance expectation, effort expectation, and amusement expectation have a positive effect on the intention to adoption of voice shopping. With respect to the four voice shopping attributes, compatibility had a positive effect on performance expectancy, effort expectancy, and playfulness expectancy. Social presence has a positive effect on playfulness expectancy. Safety has a positive effect on effort expectancy and playfulness expectancy. On the other hand, response accuracy is not significant for performance expectancy, effort expectancy, and playfulness expectancy. This study reveals the determinants of intention to adopt the new purchasing method called voice shopping, and suggests the important factors for the innovation of commerce business.

Recently, the convergence of knowledge based society and information telecommunication technologies has a rapid impact on politics, economics and various fields. Meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. Meta-analysis, can see the direction and size of the relationship between variables using the concept of the effect size. The factor determining behavioral intention of consumer in e-commerce can say that critically dependent variable. In a predictive factor determining behavioral intention is typical that perceived value and perceived risk. We conducted a meta-analysis and review of between perceived value, perceived risk and behavioral intention on e-commerce researches. This study focused a total of 33 research papers that established causal relationships in between perceived value, risk and behavioral intention on e-commerce published in Korea academic journals during 2000 and 2016. The result of the meta-analysis might be summarized that the effect size in the path from the perceived value to the behavioral intention with the effect size (r = .526), listed an explanatory power of 28%. In addition, it showed that the effect size in the path from perceived risk to the behavioral intention with the effect size (r = -.220), listed a negative explanatory power of 5%. Based on these findings, several theoretical and practical implications were suggested and discussed with the difference from previous researches.

현재 COVID-19 전염병으로 인해 전 세계적으로 오프라인 상점 대신 소비자는 전자 상거래를 선호하는 추세이다. 이에 실시간 상호작용과 상거래의 통합인 '라이브 커머스'가 각광받고 있다. 국내 라이브 커머스 시장규모가 2023년에는 10조원이 넘어설 것이라는 전망에 비하여 연구가 현저히 적은 실정이다. 이에 본 연구에선 라이브커머스의 가치와 소비자의 동기가 적극적인 소비자 행동인 E-WOM 의도를 어떻게 예측하는지 살펴보았다. 라이브 커머스의 가치로는 쾌락적가치, 실용적가치, 상징적가치와 감정적가치로 분류하였다. 또한 수단-목적사슬 이론 및 이용과 충족 이론을 적용하여 설명하였다. 종속변수인 E-WOM 의도와에 사이에서 라이브커머스의 주역할을 하는 판매자를 매개변수로 설정하였다. 이때 판매자의 상호작용성과 신뢰도로 구분짓고 연구를 설정하였다. 그리고 지각된 위험성을 조절변수로 활용하여 지각된 가치들과 판매자의 사이에서 영향이 있는지 살펴보였다. 본 연구의 설문 응답 대상은 네이버 라이브 커머스 이용 대상자 410명을 대상으로 진행하였다.
